摘要:
A photographic processing apparatus including recirculation of processing solution is provided with a variable loop additive control system comprising a treatment container in which additive solids, pastes or fluids are introduced and through which a controlled volume of processing solution is circulated from and back to the recirculating system loop. The secondary loop of the additive system allows control of the flow of processing solution through the treatment container so that the mixing of the additive into the processing solution may be controlled at a desired rate and the additive is not excessively utilized or dissipated. Various arrangements for connecting a secondary additive loop to the primary loop of a recirculating processing solution system are illustrated.
摘要:
An apparatus for processing photosensitive materials, which comprises: a tank through which a processing solution flows; a rack having integral means to facilitate its insertion and removal from the tank, the rack and the tank are relatively dimensioned so that a small volume for holding processing solution and photosensitive material is formed between the rack and the tank; means for circulating the processing solution through the small volume; and means coupled to the rack for moving the photosensitive material through the small volume.
摘要:
A low volume photographic material processing apparatus that utilizes a narrow horizontal processing channel with an upturned entrance and exit to contain processing solution within the channel. A replenishment pump calibration system is integrated into the processor so that no manual measurements or special tools are required to set replenishment solution rates.
摘要:
Textured surfaces on respective walls of racks and tanks of photographic processing apparatus reduce the frictional forces between the photosensitive material leading edge surfaces and the walls of the racks and tanks. The processing solution flows through fissures in the textured surfaces, thereby providing a solution bearing layer between the photosensitive material and the textured surfaces. This allows a greater photosensitive material leading edge impact angle with the textured walls which allows the photosensitive material to change direction unimpeded.
摘要:
A low volume photographic material processing apparatus that utilizes a narrow horizontal processing channel. The channel is formed by a repeating combination of modular squeegee pinch rollers and modular impingement slot nozzles. Photographic processing solution is introduced through the impingement slot nozzles and the squeegee pinch rollers are used to remove the processing solution from the photosensitive material and provide transport of the photosensitive material. Solution level control is achieved by drains positioned below the tops of the upturned sections.
